Specification of letters Patent.

Patented June 2t, 1914.

Application filed September 6, 1913. Serial No. 788,365.

To all whom itmajz/ concern:

lie it known that l, CLYDE S. MUNROE, a citizen of the United States,and a resident ot River Forest, in the county ot Cook and State otlllinois, have invented certain new and useful Improvements inCarburetersof which the following is a specification.

vlt has been noted by those having tamiliarity with the operation ofinternal combustion engines, especially in automobiles, that in damp andespecially foggy weather a greater proportion of air, or what amounts tothe same thing, a less proportion of `gras., may be employed and a muchmore satisfactory explosion secured.

My present. invention has for its object the provision oftacilities formoistening` the air portion of the charge for internal combustionengines, and also for controlling the amount of such moistening.

l attain the above objects by the structure illustrated in theaccompanying' drawing which is a central vertical section of myinvention.

My invention may be easily attached-to the air intake port of any ot thecarbureters now in use.

lt consists essentially of an air supply tube, '1, one end of which isconnected to the air intake port of the carbureter, above referred to.An area of the air supply tube, 1. is cut away, and about this opening;is secured the top of the funnel shaped well, the lower end ot whichextends adjacent to the bottom of a float chamber, 3. The tunnel shapedwell, 2, is filled with a suitable wicking or substance, 4, which will,through capillarity, maintain a moist area in the air supply tube, 1,over which the air reaching the, carbureter will have to pass, therebytaking up some moisture. The. amount of moisture so taken up will dependeither upon the rate of flow of the air through the air supply tube orthe` extent of the moist area in the air supply tube. As the rate offlow of the air through the air supply tube depends upon the exigenciesof the service to which the engine is put, l have provided the slidingsleeve, 5, telescoping into the air supply tube, 1, of such a lengththat when it is telescoped as far as it will enter the air supply tube,1, the moist area will be entirely covered and closed. It will beevident that the extent ofthe moist area, and thereby the amountotmoisture imparted to the air, can be determined by withdrawing thesliding sleeve, 5, to a greater or less extent from the air supply tube,1.

ln order tolkeep the` well, 2, and wicking, 4, supplied with a properamountl of moisture, neither too much nor too little, the supply port.6, ot the Hoat chamber is controlled b v a. valve, 7, upon the stem, 8,of which is an adjustable detent or nut, 9, which is adapted to beengaged by a lever arm, 10,

the other end of which lever is engaged by a float. 11, whenever theevaporation of the water in the float chamber proceeds beyond apredetermined point, thereby raising the valve, 7, from its seat untilenough water has entered the float chamber to raise the float, 1l, so asto permit. the valve, 7, to again seat. The :float chamber is suppliedwith water by means of a tube, 1Q, leading' from a tank, 13, located atsuch point as convenience may require.' i

It. will now be seen from the foregoing description. taken in connectionwith the drawings, that l have provided a. simple and otective mechanismfor in'iparting' moisture to the air composing a portion of the chargefor an internal combustion engine, and for controlling the amount ofmoisture so imparted.

Having.: described my invention, what I claim is:

1. Means for moisteninp; the air for an vinternal combustion enginecomprising an air supply tube, a well opening:` into said supply tube, awicking or capillary iillinp; for said well, a sleeve telescoping intosaid supply tube and adapted to close a `greater or less portion ot' theopening into said well. and means t'oimaintaining a constant level ofwater in said well.

2. Means t'or moisteningthe air For an internal combustion enginecomprising an air supply tube. a well opening into said supply tube, asleeve telescopingir into said supply tube and adapted to close agreater or less portion of the opening; into said well, and means formaintaining a supply of water in said well.

In testimony whereof, I have hereunto set. my hand in the presence oftwo witnesses.
